To start this whole thing off I want to say thanks to Ainslie and the rest of the 4080 crew, for all of the help and the quality work invested in to this product! This is truly an awesome box with a real Lexus OEM feel to it. On top of that, I still have room in my trunk for all my stuff with no problem. The easy design lets me pop the enclosure out in seconds if I ever need to get to my spare! I’ve got just the base GS3 package, no ML package, so I was really looking to get some low bass in the trunk. This is a low crisp bump with no distortion that I can hear. We did the whole thing in just a couple of hours, without any gotcha’s at all. We thought that it was pretty painless so we decided to do a DIY so you can see how simple it really is. I was having some camera issues the first couple of shots, so they’re blueish. Sorry…
First remove the factory engine cover on the passenger side. The engine cover is held in place by small plastic fastners. To remove the fastener, simply push in the center pin and remove.
Now, remove the battery. Using a 10mm wrench, loosen the + and – terminals. You will need a 12mm wrench to remove the battery bracket.
The plastic battery shield has two plastic wire loops that are kinda hard to un-hook. You will need a short flat head screw driver pry open the hooks
Next you will need to remove the plastic panel that is under the passenger side dash. The panel can be removed without tools. Simply pull down on each corner and un-snap the panel fastners.
You will need a wire coat hanger to puncture the rubber grommet. This will allow you to push the amps power wire through the rubber grommet. I cut a small hole in the grommet to make it easier. MAKE SURE YOU DO NOT CUT ANY OF THE FACTORY WIRES.
Next I taped the power wire to the coat hanger.
Push the coat hanger through the cut you made in the rubber grommet. It should push through fairly easy. You can spray the end of the wire with armor all to make it push through easier.
Pull the red power wire though the rubber grommet and leave approx. 2ft. in the engine bay.
Seal the hole around the power wire using clear silicone.
